This document explains how to install, configure, and set up the NI PXIe-4302 and
NI PXIe-4303 (NI PXIe-4302/4303) simultaneous filtered modules with the RM-4302
rack-mount terminal block. Driver support for the PXIe-4302/4303 was first available in
NI-DAQmx 15.1.1. Driver support for the RM-4302 was first available in NI-DAQmx 15.5. For
the list of devices supported by a specific release, refer to the NI-DAQmx Readme, available on
the version-specific download page or installation media.
Note The keying of this terminal block prevents it from connecting to other
modules that could be damaged by the voltage present on the terminal block.
However, you should only use these terminal blocks with their supported modules.

The CAL IN input connector on the rear of the RM-4302 allows you to connect a voltage
reference that can be internally routed to the analog input of each channel (AI+, AI-) on the
PXIe-4302/4303. All channels are simultaneously switched to the CAL IN by utilizing the
Calibration API within NI-DAQmx. Refer to the In-Situ Calibration section for detailed
information.

CAL BIAS
You can use the connector labeled RB1 and RB2 on the rear of the RM-4302 to reference the
CAL± input to analog ground (AIGND). For flexibility, access to both CAL+ and CAL- is
provided. The CAL BIAS+ pin connects to CAL+ and the CAL BIAS- pin connects to CAL-.
You can reference a floating voltage to AIGND by populating the RB1 position. To provide a
differential voltage that is referenced to AIGND with zero common mode, populate both RB1
and RB2 with equal value resistors. When choosing resistor values, consider the output
impedance of the external reference voltage source. Refer to Table 2 for connections.

In-Situ Calibration
The RM-4302 provides the ability to perform in-situ calibration of input channels referenced to
an external traceable voltage source that you can use to connect to the CAL IN connector. In-situ
calibration offers a means to determine measurement errors and uncertainties compared to a
traceable standard. The calibration data can be used to compensate for changes in the hardware,
resulting in a more accurate measurement. In-situ calibration can be performed before and after
test acquisition, or on a periodic schedule, to ensure data validity without physically
disconnecting any inputs from the RM-4302.
During in-situ calibration, the input channels are disconnected internally from the RJ50
connectors and connected to a calibration bus that is driven by the calibration voltage reference
connected to CAL IN±. Any PXIe-4302/4303 circuitry drift since the last full calibration will be
available through measurement of these channels. In-situ calibration performs a verification, but
not an adjustment. Therefore, the results from in-situ calibration will not rewrite the calibration
coefficients to the PXIe-4302/4303. Instead these results can be applied to the test setup, test
results, or to the PXIe-4302/4303 programmatically.
To assist you with starting development of an application with in-situ calibration, an example
program is available for download from the NI Community. Refer to ni.com/info and enter

For in-situ calibration, the following connection options are supported through NI-DAQmx as
shown in Table 3.
Table 3. Connection Options Configurable Through NI-DAQmx Connect SC Express

Purpose
Connect a voltage reference provided through CAL IN to the
analog input of each channel.
EXT PWR
The external power input connector on the rear of the RM-4302 allows you to connect a positive
voltage supply for use in powering powered sensors. The external voltage source can be either
ground referenced or floating. The EXT PWR- input is connected to the ground of the RM-4302.
Do not apply a ground referenced voltage to the EXT PWR- input; doing so can result in
excessive current conducted through the ground of the RM-4302. The EXT PWR+ and
EXT PWR- are connected to the EXT PWR+ and EXT PWR- of each RJ50 connector on the
front of the RM-4302. Refer to Table 4 for signal names and descriptions.

Signal Description
After connecting EXT PWR to a powered sensor, a short time delay may need to be introduced
in the measurement application to allow the sensor to warm up. Refer to your powered sensor
documentation for any power up settling requirements.
Current Fault Protection Reset
The positive temperature coefficient (PTC) resistors used for short circuit fault protection trip
by undergoing a large, abrupt change in resistance in response to an overcurrent. The tripped
state of the PTC is a latched state that is sustained by a small self-heating current.
The RM-4302 has one PTC per group of 8 channels. The channels in each group are 0..7, 8..15,
16..23, 24..31. A fault on any channel will cause the entire group to trip. Channels not in that
group will be unaffected.
To reset the PTC, the fault must be removed and all the current through the PTC must be
momentarily interrupted from the faulted group that contains the faulted channel. After removal
of the fault, you can interrupt the current by disconnecting EXT PWR or by disconnecting all
12

channels of the faulted group. The following three steps summarize the steps required to reset a
tripped PTC:
1.
Remove the short-circuit fault from the affected channel.
2.
Disconnect EXT PWR.
3.
After 10 seconds, reconnect EXT PWR.

Confirm SC Express Module Recognition
To confirm module recognition, complete the following steps:
Software support for the PXIe-4302/4303 is provided by NI-DAQmx. The
Read Me First: NI-DAQmx and DAQ Device Installation Guide, which you can
download at ni.com/manuals, offers step-by-step NI-DAQmx instructions for
installing software and hardware, configuring channels and tasks, and getting started
developing an application. For detailed NI software version support, refer to the
NI-DAQmx Readme.
Note
1.
Launch MAX.
2.
Expand Devices and Interfaces, and expand the chassis in which the module is located to
confirm that MAX detects the module and terminal block. The terminal block should
appear beneath its associated module. If your module or terminal block is not listed, press
<F5> to refresh MAX. If the module is still not recognized, go to ni.com/support/

Removal
Terminal Block and Cables Removal
To remove the RM-4302 and PXIe-4302/4303, complete the following steps while referring to
Figures 3 and 6:
Note
The chassis can be powered on or off when removing the terminal block.
1.
Remove the RJ50 connector cables from the terminal block.
2.
Remove any of the following connections as needed for your application:
3.
•
Disconnect the BNC cable from the PFI0 receptacle.
•
Disconnect the 4-pin calibration bias resistor connector from the 4-pin bias resistor
receptacle.
•
Disconnect the 2-pin EXT PWR connector from the 2-pin EXT PWR receptacle.
•
Disconnect the 2-pin CAL IN connector from the 2-pin CAL IN receptacle.
•
Disconnect ground wire from the ground screw.
Loosen the four jack screws and remove the SH96-96-2 cable from the terminal block and
the module.
Note
If required for your application, remove the two standoffs from the module.
4.
While supporting the terminal block, remove the four rack-mounting screws.
5.
Remove the terminal block from the rack.
6.
Store the terminal block in an antistatic protective bag.
Module Removal
Do not remove a module with the PXIe chassis powered on. Doing so can
damage the module.
Caution
To remove the PXIe-4302/4303 module, refer to Figure 9 while completing the following steps:
Note To maintain forced air cooling in the PXIe system, refer to the Maintain
Forced-Air Cooling document.
1.
Make sure that the chassis is powered off before removing the module.
2.
Loosen the captive screws on the top and bottom of the module.
Caution Do not pull the front panel to remove the module. Doing so may cause
module components to come into contact with adjacent modules, causing damage to
the modules.
